To all whom t may concern:

Be it known that I, ELMo F. KELLUM, a citizen of the United States, residing at Don Luis, in the county of Cochise and State of Arizona, have invented certain new and useful Improvements in Mining Apparatus; and I do declare the following to be a t'ull, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in mining apparatus.

One object of the invention is to provide an apparatus of this character by means of which the handling of ore lin mines will be greatly facilitated.

Another object is to provide an improved construct-ion and arrangement of ore conducting slides formed in sections and having means whereby the same are adjusted to the desired inclination and which are adapted to be readily shifted to various parts of the workings, whereby the ore may be carried or directed thereby to the permanent chutes in the mine.

Vith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement ot' parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a vertical sectional view through a portion of a mine showing the construction and arrangement ef the invention; Fig. 2 is a similar View on the line 2 2 ot Fig. 1; Fig. 3 is a vertical sectional view on the line 343 of Fig. 2; Fig. 4 is a similar view on the line 4-4 of Fig. 2; Fig. 5 is a vertical transverse sectional view on the line 5-5 of Fig. 3; Fig. 6 is a detail vertical sectional view through one of the yielding supporting devices for the slides; Fig. 7 is a detail sectional view through a portion of the frame showing the manner in which the slide supporting hooks are secured to the frame; Fig. 8 is a plan View of the parts shown in Fig. 7; Fig. 9 is a detail cross sectional view on the line 9 9 of Fig. 7; Fig. 10 is a vertical sectional view through a portion of the frame showing a modified construction of the slides; Fig. 11 is a detail vertical longitudinal sectional view through a portion of the slides shown in Fig. 10 illustrating the manner in which the sections of the slides are secured together; Fig. 12 is a cross sectional view on the line 12-12 of Fig. 11; Fig. 13 is a bottom plan view of the parts shown in Fig'. 11; Fig. 14 is a view similar to Fig. 3 showing a modified arrangement of the slides in which they are provided with doors; Fig. 15 is a vertical section taken on the line 15-15 of Fig. 14; Fig. 16 is a plan View of the lower end of the lower section ol the modified arrangement of the slide; Fig. 17 is a detail perspective view ol the door for the upper slide section of the slide; Fig. 18 is a similar view of the door or closure for the lower section of the slide. Fig. 19 is a detail perspective view ol the lower end of the lower section of the slide.

Referring more particularly to the drawings` 1 denotes a dritt in a mine in which my improved apparatus is arranged and from which the ore is removed by stoping and which may be one-thousand :feet or more under ground.

The invention is to be applied to the usual trame work 2 which is arranged in the drift or stope and which consists ot sills arranged on the floor ot' the stope and having secured thereto a series of uprights, preferably about seven feet high for each floor of the frame. said frame being any desired number of sets high, in the present instance the frame is shown as consisting ot two floors or sets The 11prights are connected at their upper ends by oppositely disposed beams or joists arranged to form the square sets. Arranged at a suitable location in the lower floor of the frame is a permanent or stationary oredischarging chute 3 having its bottom inclined toward one side in which is formed a discharge opening 4 whereby the ore may be delivered from the chute into a car or receptacle. Connected at its lower end with the upper end of the chute 3 and extending upwardly at a suitable angle and in any desired direction into the upper slides of the frame is one or more ore receiving slides 5 whereby the ore from the upper portion of the stope or dritt is carried down and discharged into the chute. The slides 5 are each formed of a series of sections of which there may be any number two being herein shown. The lower end ot the upper section o'l' the slides is of slightly less width than the upper end and the said lower end of the upper slide section over-laps and fits into the upper end of the adjoining lower section,

said engaging ends of the sections being secured together by chains 6, which are secured to the upper end of the lower section and pass through guide apertures 7 arranged in stop flanges 8, formed on reinforcing straps, or U-shaped hanger bars or stirrups 9 secured to the upper section of the slides adjacent to its lower end as shown clearly in Figs. 3 and 4. r1`he chains 6 after passing through the apertures in the flanges 8 of the hanger are engaged with hooks 10 Secured to the outer sides of the upper slide section as shown.

The upper sections of the slides are yieldingly and detachably secured to hooks or hangers 11 secured to the upper joists or beams of the frame, said upper ends of the slide sections having secured to their opposite sides spring casings 12 in which are arranged piston rods 13 having on their inner ends pistons 14 between which and the upper ends of the casings are arranged coiled springs 15. The upper ends of the piston rods 13 are slidably engaged with openings of the casings and have formed on their upper ends, eyes 16 to which are connected the lower ends of hanger chains 17, adapted to be engaged with the hooks or hangers 11 on the frame thereby yieldingly supporting the upper ends of the slides.

The lower end of each upper slide section and the upper end of eachhlower section are yieldingly supported by a bail 18 connected to the upper ends of the hanger bar or stirrup 9 and to which is connected the lower end of a chain 19, the upper portion of which is adapted to be adjustably connected to a hook 20 arranged on the lower end of a cylinder 21. In the cylinder 21 is arranged a piston rod 22, having on its inner end a piston 23 between which and the upper end of the cylinder is arranged a coiled spring 24. The outer end of the piston rod 22 is provided with an eye 25 which is connected with a hook or hanger 26 secured to the adjacent joist or beam of the frame. The lower end of the lower section of the slide is supported by means of chains 27, the lower ends of which are secured t0 a stirrup 28 on the lower end of the sections while the upper ends of said chains are secured to hangers 28 secured to the adjacent joist or beam of the frame. By thus constructing and arranging the supporting devices, it will be readily seen that the slides will be yieldingly supported and may be adjusted by lengthening or shortening the hanger chains to change the slides to any desired angle or inclination. By this arrangement of supports the position of the slides may also be readily changed so that said slides may project in any direction from the permanent chute 3 of the frame.

Adapted to be detachably secured to o-ne side of a slide section is an inclined or latis shown modified means for connecting the sections of the slides together, said connection in this instance comprising a flanged head 33 secured to the inner side of the upper end of the lower section of the slide and adapted to be engaged with a recess formed by the lower portion of a U-shaped hanger or stirrup 35 secured to the lower end of the upper section and having arranged therein a segmental seat 36 adapted to receive the head 33 on the lower section of the slide. The head 33 when thus engaged with the stirrup and seat in the upper section of the slide, is held in position by a latch 37 pivoted to the under side of the section as shown. In all other respects the construction and arrangement of the slide just described are the same as the slide described in the first part of the specification and a further description of these parts is not thought to be necessary.

The hangers with which the supporting devices and hanger chains of the slides are engaged are preferably secured to the beams or oists of the frame by means of fastening devices 3S, said devices comprising bars 39 and 40 which are hingedly connected together at their inner ends as shown. The bar 39 has its outer end bifurcated or provided with a pair of sharp fastening prongs 41 which are adapted to straddle the hangers or hooks and to be forced into the adj af cent portion of the joists or beams on each side of the hangers, as shown. The bar 40 has its outer end sharpened to form a barb or point which is forced into the beam or joist. The combined length of the two bars or sections of the fastening devices is greater than the space between the beams or joists engaged thereby so that when the prongs and point on the outer ends of the bars are engaged with the beams and the bars straightened out, said prongs and sharp end of the bars will begforced into the beams thus firmly holding the fastening devices in position and in operative engagement with the hangers whereby the latter are securely fastened to the beams.

Vhile I have herein shown and described the preferred manner of supporting the slides, it is obvious that if desired the supporting springs may be dispensed with and the slides supported at their ends by one or more hangers and supporting chains similar to the arrangement of the chains 2T which support the lower ends of the lower section of the slide thus dispensing with the bail 18. By yieldingly supporting the slides as herein shown and described the same are prevented from being broken by heavy pieces of ore or rock thrown therein or by concussion resulting from blasting operations, the slide will yield to the pressure exerted While if rigidly secured it would be liable to break. By forming the slides in sections the length of the same may be increased or diminished as required.

In the modified arrangement of the slide shown in Figs. 14 and 15 the upper section 42 of the slide has arranged thereon near its lower end a door 48 comprising a metal plate which is adapted to tit on the upper edges of the sides of the slide and which has its lower outer corners beveled or cut off at an angle as shown at 44, whereby the ends of the plate will lit closer against the inclined guiding or deflecting plate 45 arranged on the side of the slide which corresponds to the plate 29 shown in the first form of the invention. The plate or door 43 is supported in position at the end of the slide by a chain 46 adapted to be adjustably connected with a hanger 47 arranged on the adjacent over-head cross bar of the support ing frame. In the outer end of the lower section 48 of the slide is arranged a door or closure 49 comprising va curved plate 50 which tapers from one end toward the other and which has formed on its concaved side adjacent to its wider end a laterally projecting attaching liange 51 in which is secured a shaft 52. The ends of the shaft 52 project beyond the side edges of the flange 51 and form pintles one of which is engaged with a bearing aperture 53 formed in one side of the slide while the other pintle is engaged with a bearing notch 54 formed in the opposite side of the slide. The pintle or end of the shaft is held in operative enga gement with the notch 54 by means of a hook 55 which is pivoted to the adjacent side of the slide and is adapted to be hooked over the pintle or end of the shaft as shown. The pintle or end of the shaft which engages the notch 54 is preferably extended and bent at an angle to form a crank handle 56 whereby the shaft may be rocked to swing the narrow end of the plate into and out of engagement with the slide thereby closing and opening the lower or discharge end of the same. These doors 43 and 49 ar-e designed to convert the slide into a chute having discharge regulating means.

l/Vhile I have herein shown and described the slide sections having the doors or closures as a modified form of the invent-ion it is obvious that the doors or closures shown in the modification may be applied to the preferred form of the slides if desired.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
